[♛ FreemeGB] Fireflies E07 7* Nichia/ SST20/ XP-L HI Emitters 21700 Flashlight Group Buy -【 New Copper+Titanium 】

I’ve used Mouser a lot before, they’re in North Texas up near TA actually. The problem I’ve had with them in the past is that they don’t really sell specific bins, they usually sell groups. So it can be a bit iffy getting the right tint. I prefer Arrow for that reason and their shipping is usually cheaper if not free.

I use an Hakko soldering station, one of the 888 analog units. Works fine. Also picked up a hot air machine from Spark Fun, good solid unit in it’s own right.

I use Kester solder, exclusively. The .031 resin core 63/47 for soldering and their Solder Paste for re-flows and driver building. Leaded solder, for it’s lower melting point.

I never use solder flux. Never. There’s enough in the core of the small wire to do the job for me, well over 600 lights built and haven’t had a problem, don’t know how many hundreds of drivers I’ve put together. I just don’t use flux. I have some here, just never use it. I bought the flux because everyone said it was necessary, never have found that to be true. I even leave the large bevel tip on my soldering iron for almost everything. If I have a small SMD or cap or something to solder I use the corner of the tip.

I buy LED’s on-board pretty often, knowing sometimes that I’ll use it as is or sometimes I want the board for other stuff and I pull the emitter from the one it came on. Much easier to just swap out the emitter board with one that already has the emitter on it, especially for the White Flat as it’s actually a little smaller than the XP footprint and on many boards can be somewhat finicky to reflow.

I started out with an HD2010 that wouldn’t work out of the box, after some modding to it I learned it was fun, sometimes challenging, and I did more and more. I remember a neighbor once being startled that I had 29 flashlights! “How many Flashlights do you need!?” I immediately said “30”. :smiley: I’ve sold a bunch when we had issues with a new car and bought another, am back up to having over 230 lights here. And so it goes.

I should tell you that the White Flat is a tough one to be starting on. It can be tough to focus because it’s so small. Don’t get discouraged, stay at it, be careful with the soldering iron tip and avoid flux splatter onto the emitter when soldering the leads onto the board. Enjoy!

Thanks Dale!

I’ll check out Arrow for sure. I also noticed that mouser didn’t offer bins and had a single version of the emitters only.

appreciate all the answers!

lol well hopefully everything goes ok otherwise I’ll learn from good old trial and error. hopefully no rage fits

for you idk about heavy plus its gonna be for show off on my side

I recently got an Olight M2R copper edition and holy balls of fire is this thing a chunk of lead!

just for everyone’s reference how heavy a solid copper light becomes:

Standard Olight M2R 155gr 0.34-lbs (w/batt)
Copper Olight M2R 276gr 0.6-lbs (w/batt)

In a single 18650 light that’s a 78% increase in overall weight!!

Damn sure looks cool though!

LOL and one thing that was overlooked: the tailcap magnetic charger that is also a tailcap magnet…. yeah it doesn’t work so well when you make the light 80% heavier… lol hear magnet attach, let go, BOOM on floor :person_facepalming:

Y’all are funny. I chopped a Maglite to make it 1D and used a 291 gram copper pill, yes the copper alone weighs 291 grams!

Imagine if it was tungsten O__O

lol if olight could do r50 in copper that weighs 500gr with battery then im sure fireflies could do same.

Photon Fanatic once carved a square tungsten bar stock into a round one then made a flashlight out of it. Heavy little bugger it was!

I want one :smiley: I have a fidget spinner that weighs 1lb o_o so yeah im ok with copper

The brass Haikelite MT03 seems for you : 1.45 kg without batteries = 3.2 lbs :smiley:

lol 1-lb fidget spinners and 2-lb 1d maglights are definitely heavier and cooler. I just that the E07 won’t have as much market due to the weight… That or all mfg’s charge a premium for titanium which is why they want to desperately use it.

on that note: did you all hear that the GT4 is currently spec’d to weigh a ridiculous 7-lbs!

lol the BLF GT it’s based off only weighs 4-lbs

gotta love slabs o metal to get that heat outta there!

Imagine a luxury version of the GT4 in solid copper! :money_mouth_face:

I’d buy one!

buying it asap O_O
